The fault appears after 11 failed regeneration attempts when driving.
Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary
– Carry out an After-Sales regeneration.
– Follow the procedure for command SC017 Particle filter regeneration (see Interpretation of commands).
– At the end of After-Sales regeneration, if the CLIP diagnostic tool indicates that you must replace the particle
filter, perform a oil change and replace the oil filter.
Explain to the customer the procedure for regeneration when driving to limit future garage repairs: see PART D in
the interpretation of DF312 Speed request.

NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present:
– the special regenerate particle filter warning light is lit or a warning message is
displayed on the instrument panel.
– The vehicle needs to be driven specially to activate particle filter regeneration during
driving.
Priorities when dealing with a number of faults:
Firstly, deal with the following faults:
– DF308 Particle filter clogged if it is present or stored.
– DF311 Failed regenerations limit exceeded if it is present.
– DF315 Particle filter diff* pressure sensor if it is present or stored.
The fault appears after:
– 7 failed regeneration attempts when driving and the weight of soot in the particle filter is greater than
21 g.
– the weight of soot in the particle filter is greater than 58 g.
PART A:
The flow chart on the following page can be used to analyse the driving profile and causes of the activation of this
fault.

Repair request with DF312 present or stored ONLY
Read the information from the sub-function Particle filter histo*: PR784 to PR793 DF312 No. 1 to No. 10 records
Are PR784 to PR793 all equal to 0 miles (0 km)?
Among these parameters (PR784 to PR793):
– Find the parameter with the highest mileage: it is the Mileage of the last DF312.
– Note the parameter index on the order of repair with the relevant mileage value.
E.g.: PR787 = 2794 miles (4657 Km)
Read the information in the Particle filter histo* sub-function:
PR794 to PR803 Stored regeneration failures No. 1 to No. 10.
Does at least one of parameters PR794 to PR803 = 19659 miles
(32766 Km)?
Identify the distance(s) from the values of parameters PR794 to PR803 Stored regeneration failures No. 1
to No. 10, included between the Mileage of the last DF312 and the Mileage of the last DF312 - 120 miles
(200 km). These are the mileages of the last failures.
Example: 2674 miles (4457 km) < PR801 = 2760 miles (4600 km) < 2794 miles (4657 km)

PART B
1. No particle filter regeneration.
2. Write on the repair order the parameter and status relating to the last failure:
Mileage of last DF312
Mileage of last failures
Engine statuses of last failures
E.g.: PR787 = 2794 miles (4657 km); PR801 = 2760 miles (4600 km); engine status = STOPPED
3. Interpretation of the values written on the repair order by the service advisor for the customer:
Before the last time the Particle Filter message or warning light illuminated (appeared at the Mileage of the
last DF312), the customer had not adhered to the driving recommendations: the failure that occurred at the
Mileage of the last failure is due to the engine being switched off.
4. Explain to the customer the procedure to turn off the warning light, making use of the parameters noted in the
repair order: see PA R T D.
PART C
Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary
Carry out an After-Sales regeneration with the consent of the Techline.
Follow the procedure for command SC017 Particle filter regeneration (see Interpretation of commands).
Explain to the customer the procedure for regeneration when driving to avoid unnecessary repairs: see PART D.

PART D
Procedure to switch off the Particle filter message or warning light on the instrument panel
The customer must carry out a specific driving operation (cf. vehicle user manual) that consists of:
1. When the engine is warm, drive at a speed greater than 36 mph (60 km/h) for 1 minute to trigger the
regeneration procedure.
2. Keep driving at an average speed of 36 mph (60 Km/h), until the particle filter message or warning light on
the instrument panel goes out. In order for the procedure to succeed, it is necessary to drive without stopping
the engine or leaving the engine running at idle speed for an extended period of time. The regeneration time
depends on the vehicle and driving conditions but should last for 20 minutes maximum.
3. If regeneration when driving fails (the warning light has not switched off or the service warning light has come
on), carry out a particle filter regeneration in the Renault dealership. Run command SC017 Particle filter
regeneration (see interpretation of commands).
Check that there are no leaks or blockages in the exhaust pipe.
Repair if necessary
If the fault is still present, contact the Techline.

NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present:
–the level 1 warning light is lit,
–the OBD warning light will come on after three consecutive driving cycles (start
+ 5 seconds + switch off the ignition switched and wait 1 minute),
– the particle filter fault finding procedure is inhibited,
– particle filter regeneration is inhibited.
Priorities when dealing with a number of faults:
– DF315 if it is present.
– DF308 "Particle filter clogged" if DF315 is stored and DF308 is present.
– DF011 Sensor supply voltage no. 1 if it is present or stored.
